The Buffalo News is reporting that the deal is for two years with a maximum
value of around $13 million.

He is expected to compete with Tarvaris Jackson, who signed a one-year deal
with the club last month, for the starting job.

Kolb led the Arizona Cardinals to a 4-0 start last season, but was knocked out
for the rest of the season in a game against Buffalo as he suffered detached
ribs and a sprained shoulder. He also missed a total of five games in 2011 and
2010 with separate concussions.

Over six seasons in the NFL, the second-round draft pick of the Philadelphia
Eagles in 2007 has completed 59.5 percent of his pass attempts for 5,206 yards
along with 28 touchdowns and 25 interceptions in 34 games with the Eagles and
Cardinals.
